Honda 2 Wheelers India — honda grazia rc and no. plate not received

I have purchased honda grazzia from kabir honda showroom ballabgarh on 4th dec 2017. But it has been more then 50 days. I have not recived my rc and no. Plate. Once they said they dont know when the rc will come. The showroom people have stopped picking up my phone calls. Its pathetic and biggest mistake of my life to purchase scooty from this showroom. Moerever the showroom people don't handle customer issues like providing documents and bills timely to the customer during the purchase of the vehicle. First they said the bill could not be generated within 2 days and they will provide the bill at my home themselves. When contacted they said will take a week and i have to come to the showroom to pick the bill. Moerver i have not yet got my complete asssessoriez of the scooty till date. Please see to this matter and resolve it. If possible cancel the licence of the showroom (Kabir honda ballabgarh).
